Finally, youll need some sort of indicator to let you know when the batteries are done charging. Once youve made the holes, screw in two screws (one on each side) to secure the charger in place. Make sure that the power source you choose can provide enough current for your needs. Your should derate the full-wave rectifier DC current output to about 60% or less of the transformer AC rating due to the high RMS (peak) current that a rectifier generates, which can overheat the transformer. Cut as close to the jack as possible so that you have as much wire to work with as possible. For the 12v battery charger without transformer, you will need a 12v lead acid battery, a 12v solar panel, a 12vdc power supply, a diode, some alligator clips, and some wire. The item also requires the appropriate under/over voltage protection, indicator lights etc. SCR (Thyristor) Rectifiers First of all, the two SCRs (silicon controlled rectifiers or thyristors) are connected with their anodes (stud or tab) groundedthis makes for excellent thermal transfer because no insulating hardware is required (if it is permissible to connect the negative terminal of the charger directly to the steel enclosure).
